Fire crews have the western stretch of a deadly wildfire north of Los Angeles under control and the blaze is no longer threatening homes in the region.

The fire is 49 percent contained after firefighters built protective lines near Santa Clarita. Now, crews are working to slow the flames' eastern march into the San Gabriel Wilderness.

The weekend weather could offer some respite to weary firefighters since cooler temperatures and slightly higher humidity are forecast.

Also Saturday, arson investigators are working to analyze clues found at a charred hillside near Angeles Crest Highway, including incendiary material reported to have been found there. Two firefighters died in the blaze and sheriff's detectives opened a homicide investigation after the fire was ruled an arson earlier this week.

The blaze has destroyed at least 76 homes and burned nearly 242 square miles of the Angeles National Forest.
